- PN series (high heat resistance)
What is the LEONA™ PN series?
LEONA™ P Series is a high-heat-resistant grade based on high-performance polyamide (PPA). Among PPA materials, it offers one of the highest levels of heat resistance and exhibits excellent mechanical properties under high-temperature conditions.
This series enables use in high-temperature environments and compatibility with reflow soldering processes, which could not be achieved with conventional Leona grades.
Currently, three grade families are under development:
- Glass fiber–reinforced, flame-retardant: PN Series (commercially available)
- Glass fiber–reinforced, non-flame-retardant: PG Series (under development)
- Carbon fiber–reinforced: PC Series (under development)
The glass fiber–reinforced, flame-retardant PN Series has now been commercially launched.
This page introduces the key features of the PN Series.
What Is LEONA™PN Series
LEONA™ PN Series uses a halogen-free flame retardant and has achieved UL 94 V-0 flammability rating at 0.30 mm thickness.
It also offers a CTI of 600 V (PLC 0), contributing to enhanced safety and miniaturization of high-voltage components.
With a melting point exceeding 320°C, the PN Series is suitable for use in reflow soldering processes.
High-heat-resistant PPA materials are increasingly used in electrical and electronic components as well as automotive parts. This trend is driven by rising operating temperatures resulting from higher integration density aimed at component miniaturization.
